Introduction to Digital Linear
Heat Detection Technology
Protectowire Linear Heat etector is a sensor cable that detects heat anywhere along its length. The sensor
cable is comprised of two steel conductors individually insulated with a heat sensitive polymer. The insulated
conductors are twisted together to impose a spring pressure between them, then wrapped with a protective
tape and finished with an outer jacket suitable for the environment in which the etector will be installed.
Invented and Patented by The Protectowire Co., Inc. in 1938, igital Linear Heat etectors have been uti-
lized in the fire protection industry for over 80 years.
Ideally suited to industrial high risk hazards as well as many types of commercial applications, Protectowire
Linear Heat etector has unique advantages over other types of detectors, especially when difficult installation
factors or severe environmental conditions are present.
How Digital Linear Heat Detection Works
Digital Linear Heat Detection Operation
To understand how igital Linear Heat etectors work it is important to have an understanding of how they
are constructed.
Figure 1 - igital linear heat detectors are constructed of a twisted pair of spring conductors
coated with a thermoplastic coating designed to soften at a specific temperature. An initiating device circuit
monitors a length of this detector installed in an area to be protected.
Figure 1

2
Figure 2 - When the detector is exposed to heat at a point along its length the thermoplastic coating at that
point softens and the spring pressure between conductors causes them to contact each other creating a short
circuit. The short circuit is sensed by the initiation device circuit which reports an alarm.
Figure 2
This very reliable method of detection has been in use for over 75 years in the fire protection industry and is
ideally suited to industrial high risk hazards as well as many types of commercial applications.

The PIM-530 Series
Interface Module
General Information
The Protectowire PIM-530 is a detection control module that is an interface between a main fire alarm
control panel detection circuit or addressable node and Protectowire igital Linear Heat etector. The
module provides one (1) supervised detection circuit that may be field wired for either Class A (Style ) or
Class B (Style B) service. The alarm initiating circuit is capable of operating up to 6,560 feet (2,000m) of
Protectowire igital Linear Heat etector. The PIM-530 initiating circuit is designed to monitor Protectowire
igital Linear Heat etector and also supports other types of normally open contact alarm initiating devices.
Two wire smoke detectors which require initiating device circuit power to operate are not supported.
Description
The PIM-530 operates using standard initiating device circuit technology. When paired with Protectowire
igital Linear Heat etectors, the module provides full supervision and alarm condition monitoring of the
detector loop.
The PIM-530 is designed for easy installation and is available in an optional NEMA-4X rated enclosure for
mounting outside of the host fire alarm control panel or remotely near the hazard to be protected. In order to
ensure proper operation, each PIM-530 module requires regulated resettable external power which is normally
provided by the host fire alarm panel. Each module contains a green “Power-On” LE indicator, one (1) red
“Alarm” LE indicator, and one (1) yellow “Trouble” LE indicator. One (1) set of Form C alarm contacts
and one (1) set of Form C trouble contacts are provided to connect the unit to the host fire alarm panel. The
module also provides two 4-20mA outputs. One allows monitoring of the module status and the other for
alarm point location information.
In addition to the features listed above the standard version of the module, model PIM-530, provides a 4x20
LE backlit LC display and navigation buttons for access to a complete menu driven user interface. Also
available is model PIM-530LT which is intended for use in low temperature applications. The LT version of
the interface module contains no LC display or navigation buttons and no menu accessible user interface.

4-20mA Output Information
Description - The PIM-530 provides two 4-20mA outputs that allow for monitoring of the module status
and active alarm point location reading. These outputs are intended for annunciation purposes only. Module
monitoring is intended to be accomplished using the on board supplied dry contacts connected to a listed or
approved fire detection control panel initiating device circuit.
For Class “A” wiring configurations the status output will also indicate which detector input is currently being
measured by the alarm point location meter. The measurement is alternated between inputs approximately
every 3 seconds with the status output indicating which input is currently being read.
The output levels are detailed below.
Status Output - 4-20mA Output Loop 1:
Fault – 4mA or less
Open – 6mA
Normal – 10mA
Initiating evice Circuit Out Alarm – 17mA
Initiating evice Circuit Return Alarm – 19mA
Note: For systems employing an isolated power source for the 4-20mA loops; Module Power Failure will
report at greater than or equal to 20mA
Alarm Point Location Output – 4-20mA Output Loop 2:
4-20mA Full Scale corresponds to 0-8,000 Feet.
4mA = 0 Feet – 20mA = 8,000 Feet
To calculate current to distance in feet use the following formula:
Current in mA = (I)
(I - 4) / 0.002 = istance in Feet
To convert to Meters:
istance in Feet x 0.3048

Installation and Wiring
Mounting and location – The PIM-530 can be provided as a complete module assembly for installation in
a customer supplied enclosure or pre-mounted in a factory supplied enclosure. Please refer to the specifications
section for enclosure information. When mounting the PIM-530 please follow the installation guidelines
below.
The PIM-530 interface module shall be located in a clean, dry, vibration free environment and shall not be

Installation and Wiring – (continued)
Wire the system according to this manual using Figure 3 as reference. Wiring should be in accordance with
applicable National and/or Local Electrical Fire Alarm Codes.
Detector Wiring – The PIM-530 provides one (1) supervised detection circuit that may be field wired for
either Class A (Style ) or Class B (Style B) service. The alarm initiating circuit is capable of operating up to
6,560 feet (2,000m) of Protectowire igital Linear Heat etector. The PIM-530 initiating circuit is designed
to monitor Protectowire igital Heat etector and also supports other types of normally open contact alarm
initiating devices. Two wire smoke detectors which require initiating device circuit power to operate are not
supported.
Step 1 - Remove the factory supplied 10K 1/2w end-of-line resistor (ELR) from terminal J11 OUT (+)
and (–). Retain this resistor for installation at the end of the detector run as shown in the Class “B”
field wiring diagram on this page. For Class “A” configuration the ELR shall be removed and
discarded.
Step 2 - Connect the Protectowire Linear Heat etector to the PIM-530 interface module at terminal
J11 as shown in the field wiring diagram (Figure 3) in either a Class “B” or Class “A” configuration.
Wiring Terminations – All terminations and or splices in the detector loop must be made utilizing
Protectowire recommended terminals. Only zone boxes and splicing connectors specifically recommended by
The Protectowire Co., Inc. shall be utilized.
Interface Wiring – The PIM-530 is a detection control module that is an interface between a main fire alarm
control panel detection circuit or addressable node and Protectowire igital Linear Heat etector. The most
common interface connections utilize the two form “C” contacts provided for Fault and Alarm conditions.
Step 3 - Connect the host panel’s initiating device circuit(s) to terminals J13 as shown on the field
wiring diagram (Figure 3). Reference the host panel wiring specifications for correct wiring
configuration and requirements.
Power Wiring – The PIM-530 requires external regulated, uninterruptible C power. The module provides
an internal switching regulator which supports input voltages between 12 to 24 V C (+10% / -15%) @ 1.6
Watt. To implement remote resetting of the module from the host panel, the supplied power may be interrupt-
ed during the hosts panels reset sequence. This “resettable power” function is the only means of resetting PIM-
530LT version of the module which is provided without an integrated user interface.
Step 4 – Connect a regulated 12-24V C resettable power supply to terminal J10 as shown on the field
wiring diagram (Figure 3). See the “Specification” section for power requirements.
Important ! – The PIM-530 must be connected to earth ground via the J10 GN terminal as depicted in the
field wiring diagram. If earth ground is unavailable, for example in vehicle applications, the GN and COM
terminals must be connected to each other with a jumper wire.

Installation and Wiring – (continued)
4-20mA Output Wiring – The PIM-530 provides two 4-20mA outputs which allow the status of the module
to be remotely monitored. See the specifications section of this manual and the 4-20mA Output Information
section for additional information on each outputs function.
Step 1 – Connect a regulated 12-24V C regulated power voltage to Loop -1 terminal J9 +V and to
terminal J9 RTN as shown on the field wiring diagram (Figure 3). Repeat this step for Loop - 2.
Step 2 – Select a conditioning resistor value from the list below based on the supply voltage and the
loop resistance of the measurement wiring. The total loop resistance including the resistor value should
not exceed the resistance value shown for the supply voltage.
Supply @ 12V – 300 Ohms
Supply @ 24 – 800 Ohms
Step 3 – Connect the measurement device wiring and load resistor selected in step 2 to terminals J9
OUT and J9 RTN as shown on field wiring diagram (Figure 3). Repeat this step for Loop 2 if second
loop is to be monitored also.

Configuration and Feature Selection
Configuration Prerequisites - The PIM-530 must be configured and tested before service. Configuration
and testing of detection equipment shall be performed by competent, qualified personnel having jurisdiction
over this detection equipment. Monitoring equipment connected to the PIM-530 should be bypassed or dis-
abled prior to setup to avoid unintended activation of the monitoring equipment.
Display, Menus and Navigation Controls – The standard version of the PIM-530 has an integrated LC
display and navigation controls which allow user access to the detectors status information and the setup
menu.
Navigation Switches Status Screen
Note: The PIM-530LT version of the detector is provided without an integrated LC display or navigation
controls. The PIM-530LT version of the detector can be field programmed with a separate external program-
ming interface.
Initial Power p – When power is applied, PIM-530 will go through a short boot sequence. The green
power on LE will illuminate and the boot screen will display the currently configured detector type followed
by the firmware version and date. When the boot sequence is complete the module will display a normal status
message.
Boot Screen Status Screen
Accessing the Menu – The PIM-530 menu is password protected. The two levels of access are User level
(USER) and Technician (TECH) level. User level access is limited to etector Reset and Event History view-
ing functions. Technician level access permits full access to the configuration menu.
To enter the Menu press the center navigation button labeled “OK” and the password entry screen will appear.
Note: uring menu access detection monitoring is halted. While detection monitoring is halted the PIM-530
will report a fault condition via the “FAULT” led indicator and the fault contacts will transfer. Normal standby
operation will be restored once the menu is exited and detection monitoring resumes.

Use the left and right navigation buttons to select each character and the up and down navigation buttons to
change the character. Once all characters have been entered press the center navigation button labeled OK to
access the menu.
Entering an incorrect password will produce a password entry error and the user will be returned to the pass-
word entry screen. Press the escape ESC key at any time to return to the main display.
The PIM-530 is supplied from the factory with default passwords for the user and technician level. uring
initial setup it is recommended the technician level password be set to a new value to prevent unauthorized
access to the settings. The User level password can also be set to a new value at the installer’s discretion but is
not required in most cases.
efault User level password = 1000
efault Technician level password = 2000
Once the correct user level password has been entered the setup menu will be displayed. The current user level
will be shown in the setup menu heading as seen below. The available menu items are numbered and can be
accessed by using the up and down navigation keys. The “>” symbol indicates the currently selected menu
item.
The setup menu can be exited at any time by either pressing the “ESC” key or by selecting the “1: EXIT”
menu item and then pressing the “OK” key. While accessing the setup menu the inputs will remain inactive.
After 30 seconds of inactivity the module will automatically exit the setup menu and resume normal operation.
Menu Screen
Resetting the Detector – Once an alarm or short fault condition has been detected the module status will
remain in that condition until the detector has been reset. To reset the detector enter the setup menu and
select the “2: RESET ETECTOR” option.

The display will show an “EVENT CLEARE ” message while the detector resets. All outputs should return
to normal standby states. Once the reset process has completed the display will return to a normal standby
display.
Note: If a detectable condition exists in the field, for example a short in the linear heat detector, the
condition must be repaired before resetting the detector. Failure to do so will result in the condition being
detected again after a reset completes.
Open conditions do not require the detector be reset. Once the open condition is repaired in the field the
module will return to a normal standby automatically.
Detector Type Selection – The PIM-530 is designed to operate with all the available detector types (PHSC
& PLR) in the igital Heat etector family. A etector Type selection menu has been included to allow for
future support of other detector types.
Currently the PIM-530 has no selectable options in the etector Type Selection screen and will display the
detector type configured for PHSC (Protectowire Heat Sensitive Cable) and then return the user to
the main menu.

Display nits – The PIM-530 can be configured to display measurement information in either Standard
(Temperature = ˚F, istance = Feet) or Metric units (Temperature = ˚C, istance = Meters). Select a unit type
by entering the setup menu and selecting the “4: ISPLAY UNITS” menu item and press the “OK” button.
The units selection screen will be displayed.
Using the Up/ own navigation buttons select the desired units from the drop down list. The currently select-
ed type is followed by the “>” character. Once your selection is made press the “OK” button and you will be
returned to the main setup menu. Choose the “1: EXIT” menu item and press “OK” to return to the status
display.
Alarm Point Location (APL) Setup – The PIM-530 features an integrated Alarm Point Location Meter
(APL) which will identify the distance from the beginning of a detector run to the shorted portion of the
detector. Field calibration of the Alarm Point Location reading increases accuracy and provides the user a
means to compensate for changes introduced by addition of extension cable and also reading variations due to
ambient temperature.
Before calibrating the Alarm Point Location feature please follow these guidelines:
1. Calibration should be performed at the expected nominal ambient temperature for the installed
detector. For example, refrigerated storage installations should be calibrated after cool down.
2. To perform a calibration you must have access to the connections at the beginning of the detector
run and the end of the detector run.
3. All shorts placed in the detector loop during calibration should be created with a low resistance
jumper wire screwed directly under the junction terminals to ensure a true short. Using clip leads or
pressing jumpers across terminations does not insure a true short and can affect calibration accuracy.
This method is the suggested best practice for shorting the detector loop and should be used to
insure the best results.
Before starting the APL Calibration routine the detection loop must be installed and confirmed to be in a
NORMAL standby condition. Figure 4 depicts a typical Class B field wiring arrangement. Figure 4A depicts a
typical Class A field wiring arrangement. The procedure is the same for both Class B and A wiring configura-
tions unless otherwise noted. Where feed wire is not utilized shorts should be placed across the detector termi-
nations on the PIM-530 inputs.

Press the OK button to begin the ZERO distance calibration. The module will measure the resistance to the
beginning of the detector run and offset future readings by this value.
Zero Calibration Measurement Screen APL Setup Menu Screen
Once the ZERO distance calibration has been completed you will automatically be returned to the “APL
SETUP:” screen. Remove the short placed across the beginning of the detector run and proceed to Step 2.
Step 2 - Place a short across the end (END distance) of the digital linear heat detector run as depicted in
Figure 6 for Class B and as depicted in Figure 7 for Class A.

To calibrate the Alarm Point Location END point and SPAN distance enter the setup menu and select the “5:
APL SETUP” menu item and press the “OK” button. The “APL SETUP:” screen will be displayed. Select the
“2: CAL END PT./SPAN” option from the menu and press the “OK” button. The AUTO CALIBRATE:
END Distance message will be displayed.
Press the OK button to begin the END distance calibration. In the case of Class A installation (Figure 7)
the module will first measure feed cable resistance between the Input 2 terminals and the detectors end
terminations.

The module will then measure the resistance of the linear heat detector and store it to be used in the final
span adjustment of Step 3.
End Calibration Start Screen End Calibration Return Measurement Screen
Step 3 – When the PIM-530 has completed all calibration measurements the detector end distance adjustment
screen will be displayed. This screen displays the current measured distance to the end of the detector using the
default distance multiplier and offsets obtained in steps 1 and 2. The distance should be very close to the actu-
al installed detector length at this point. To improve the accuracy of the measurement the actual installed
length of detector can be entered in place of the displayed reading.
End Calibration Detector Measurement Screen End Distance Adjustment Screen
Enter the new end distance value by using the Left and Right navigation buttons to select a digit of the
displayed value and use the Up and Down navigation buttons to change the value.
Once the desired distance has been entered, press OK to accept the distance reading and calculate the new
calibration value. At this point the calibration process is completed and the APL SETUP menu is displayed.
Remove the short placed across the end of the detector run.
View the current calibration settings by selecting the “3: VIEW CURRENT CAL” option from the APL
